Big Data as a Service (BDaaS) means outsourcing various big data functions to the cloud, which includes supply of data, analytical tools to interrogate and analysis the data. Advantages of outsourcing your analytical activities are:

·         Organizations can save money spent on components and infrastructure and time.

·         Storing large quantity of information requires an ongoing investment of time and resources.  But by using BDaaS, organizations can concentrate on business only.

·         When data is stored on a BDaaS service provider server they are responsible for it.

·         Pay only for services you use on the basis of time used or the cost of compliance and data protection.
